, IMPROVEMENT IN APPARATUS FOR CARBU'RETING AIR.

The Schedule referred to in thse Lettera Patent and making part of the same.

To all lwhom itmaycocern:

Beit known that I, JAMES I". SPENOE, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved-Machine for Carf bursting Air; and I do hereby declare' that the fol- Ylowing is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of `this specification, in which- Figure 1 isa sectional elevation Figure 2 is a sectional elevation in the line d d, fig. 1; and

Figure 3 isa plan view ofthe chamber that contains iron iilings, taken in tlie line b b, lig. 1. 1

This invention consists iu a fan-wheel whose wings u are each provided with a series of parallel pipes, thronglrwhich, when the wheel is more than half submerged in a reservoir of water, and rotated there' in, air is forced into the axial chamber 'in the interior of the wheel by the rising of the water in the pipes as the latter descend.

The invention also-consists in a reservoir for` holding the water in which the said itu-wheel revolves, made with hollow walls, which serve as carbureting-chambers, furthe purpose of causingan even temperature to he maintained in such carbnreting-chambers by the water in the reservoir; and p The invention also consists in a process of purifying the gas after it emerges from the carbureter, `by passingv it over a vesselcontaining sulphuric acid, and of dry- `ing the gas subsequent to such purification, bypassing it through a volute-chamber containing iron turnings immersed in water, by which processes the illuminating capacity of thc'gas is also increased.

In therdrawing-V- y a is the water-reservoir. I, the wings of the fan-wheel, which turns in the reservoir.

` c, the pipes attached to each wing. d, the hollow walls of thereservoir, forming the carbureter.

e, an'air-chamber attached to one end of the fanwheel.

f, a pipe leading from said air-chamber to the earbureter d.

. m, Va pipe leading from the carburreter to an yupper reservoir, i.

k, the vessel, within snch'upper reservoir, which contains sulphuric acid.

n, the volute-chamber, beneath the vessel k, which contains iron turnings.

0, pipes leading downward out of the volute-chainber.

r, the ppeby which gas iiows fromtlie reservoiri tothe burner.

As the fan-wheel revolves, the water entering the mouths of the descending `pipes c, forces air through the same into the axial chamber of the wheel; theng the air passes into, the chamber e, whence it ilows, by the pipe f, to the carbureter, passing through whichV it rises, `thrcuglrthe pipe m., to the reservoir i, in which it passes over the open vessel k, containing sulphuric acid, where itis pu'rilied. rEheuce the gaspas'ses` downward into the volute-chamber n, where it is driedby the iron turnings. Finally, it flows awayjn a con# dition itf for use.

The pipes c are of such length and curvature that,

before the air ceases flowing out of one set, the mouths of the next set following enter the water, and a blastissues vfrom them also; hence there is always a steady current of air flowing into the axial-chamber of the fan-wheel.

I am aware that sulphuric acid and iron tnrnings have been used together for the purposeof generating gas. I use them separately, `however--the acidjfor purifying gas that has already been made, and the iron for'drying the same. Y

Having thus described my invent-ion, v

YVhat I claim as new, and desire to secure by Letters Patent, is p y 1. The reservoir a, provided with hollow walls d, arranged to serve as carbureting-chambcrs, substantially as described. Y

2. The process of. purifying and `drying carbureted set my hand this 11th Yday ot' May, 1870.

JAMES F. SPENCE.
